The question of whether we’ll be uploading our consciousness to a computer is no longer if. It’s probably when. That’s because these digital consciousnesses – our essences – will likely be the product of an AI’s interpretation of ourselves. The breadcrumbs we’ll leave across digital files, images, videos, audio recordings, and, of course, all that social media will be an ample resource to reconstruct you.
I doubt it will come close to that, it would probably be a very bad copy. I doubt even the most facebook addicted person would put out enough information for the AI to make a good copy of them as a person. Their voice and face, yes, but I imagine talking to them would be just as infuriating as talking to an AI model of today.
